Have used H&R Block for more than 20 years. Software is easy to install and use. Love the part of the program that allows you to estimate the value of your donations.
mostly a good product except for two things: navigation and fixing forms. back button often doesn't go back to where you just came from, sometimes a dialog that you weren't working on (navigation). worksheets are sometimes flagged for errors, you fill them in but still get flagged for errors. there is no explanation about what is wrong when the highlighted areas are already filled in.
There is one flaw in the software for the last 3 years at least. I have a Misc. Deduction for "Federal Estate Tax". It doesn't transfer this deduction to my state return (Alabama Form 40). I have to override the Misc. Deduction space on my Alabama form to add this deduction.
